1 My invention relates to brackets 'to be attached to ladders, and moreparticularly to ladder brackets which provide platform space, and willact as a support for scaffolds. I

The prime object of the invention is to pro- 5 vide a ladder bracketwhich may be supportably attached to any usual ladder, and when soattached, will provide a standing platform for a worker.

Another object is to provide an article of this class, which may beattached one to each of two spaced leaning ladders, and when soattached, the two will act as a support for the ends of two scaffoldboards.

A further object is to provide an article of this formed into thecompleted article merely by proper bending.

Further objects will be apparent from the following description whentaken in conjunction with the accompanying single sheet of drawings,

wherein:

Figure 1 is a diagrammatic view of two usual ladders leaning against awall, and showing in perspective, one article of the inventionoperatively installed upon each ladder; and

Figure 2 is a perspective view of the device operatively installed upona usual rung-type ladder. Like characters of reference designate likeparts in the figures wherein they occur.

In the drawings:

The reference numeral l indicates a vertical 40 wall aaginst which areleaning the upper ends of two spaced ladders 2. The ladders are of usualtype, each consisting of parallel side members 3 between which arerigidly mounted vertically spaced horizontal rungs 4. I

The article of the invention is adapted to be installed upon and to besupported by the rungs 4 of the ladder, and consists of the followingdescribed integral parts or portions.

A horizontal fiat upper platform III; a similar lower platform II; and astraight frame member or connector I! attaching the two platformsrigidly together in spaced relation. The platforms l0 and II aresubstantially identical, but extend horizontally from opposite sides ofthe frame 1 Claims. (Cl. 248-238) member I 2, andthe outer end of eachis provided with two arcuate and downwardly extending hooks l3. In thepreferred embodiment shown, the platforms are shown as having theirouter portions bifurcated by a V-shaped notch l4, but if desired, thenotch could well be eliminated, and the hooks I 3 of each platform couldextend entirely across the platform.

The article is installed by merely engaging the hooks l3 over two rungs4 of the ladder, with the frame member l2 passing through the ladderadjacent an intermediate rung. The frame member I2 is provided with ahook l5 for engagement over the intervening rung, as best shown in Fig.2.

When thus installed, the four hooks l3 and the single hook l5 act toprevent any rocking or swinging movement of the device. The platform Illmay be used as a standing or sitting surface for a workman, and thelower platform I I may Q be used to support working materials such aspaint containers, caulking material, and the like.

When usedas a, scaffold support, one of the devices is installed uponeach of two spaced ladders (Fig. 1), and a board l6 may then besupported by the two. The upper platforms are each equipped with anupstanding lug or flange I! to prevent lateral slipping of the board.

Obviously certain modifications of the article could well be madewithout detrimentally affecting its efficiency, and without avoiding theprinciple upon which it is constructed nor the prin-' ciple upon whichit functions, and I therefore do not wish to be limited to the specificembodiment shown and described herein, further than I am limited by thescope of the appended claims.

While not so shown in the drawings, the hook I 5 and the lug I! couldwell be cut from the body of the frame member I 2 and the platform,respectively. This would permit the entire article to be die-stampedfrom sheet material at a. single operation.

I claim:

1. As an article of manufacture, a unitary structure including? twovertically spaced horizontal platforms, the upper one partiallyoverlying the lower one; a connector extending between opposite ends ofsaid platforms and rigidly holding them with their upper surfaces inparallel relation; a depending hook at the free end of each platform;and an outwardly extending downwardly projecting stabilizing hookintermediate the ends of said connector.

2. Structure as specified in claim 1, and an upstanding flange carriedby the connected end of the upper platform.
